A hardware ZABBIX Agent made with PIC18F67J60 microcontroller

[just2blue4u]

That's a really cool thing!
I am really looking for a way to monitor our server room's temperature.
So i need that device and a seperate temperature sensor?

Can i build it by myself?

What do you want to buid, device or sensors ?

Everything:
The device, with a temperature sensor onboard...

Depending of your skill ... (MCU have TQFP64 package)

I can put one temperature sensor on the board, but it's not recommended becouse my MCU (PIC18F67J60) work at 50 deg C and temperature will be transmited to sensor through board ....

The right choses is sensor with one or two meters of cable !

Hi Florin,

Say, are you planning to make a board using PoE instead of a seperate power source?

[yo2lio]

Unfortunately I can't do this now !

HWZA (Hardware Zabbix Agent) LIVE

HWZA (Hardware Zabbix Agent) LIVE

WEB : http://ip-watcher.dyndns.info:10000/

Zabbix Agent : http://ip-watcher.dyndns.info/ PORT 10050

Software have two mode for Digital inputs (Temperature sensors or Counters) configurable through software (windows program) and one mode for Analog inputs ( Voltage measurements up to 24 V DC)

Available commands for test are :

agent.ping - return always 1

tns[0] - return voltage*100 applied on AN0 (analog input) (max 24 V)
tns[1] - return voltage*100 applied on AN1 (analog input) (max 24 V)
tns[2] - return voltage*100 applied on AN2 (analog input) (max 24 V)
tns[3] - return DC IN voltage*100 (Power DC source)

tmp[0] - return temperature*100 for sensor (DS18B20) connected at Dig0 pin (digital input)
tmp[1] - return temperature*100 for sensor (DS18B20) connected at Dig1 pin (digital input)
tmp[2] - return temperature*100 for sensor (DS18B20) connected at Dig2 pin (digital input)

cnt[0] - Counter , polling interval 10 times/second - only in counter mode (Dig0)
cnt[1] - Counter , polling interval 10 times/second - only in counter mode (Dig1)
cnt[2] - Counter , polling interval 10 times/second - only in counter mode (Dig2)

cnt[3] - Counter , polling interval 1 times/second - (AN0)
cnt[4] - Counter , polling interval 1 times/second - (AN1)
cnt[5] - Counter , polling interval 1 times/second - (AN2)

pin[0] - return logic state of Dig0 pin (0/1) - only in counter mode
pin[1] - return logic state of Dig1 pin (0/1) - only in counter mode
pin[2] - return logic state of Dig2 pin (0/1) - only in counter mode

pin[3] - return logic state of AN0 pin (0/1) - If voltage > 2.5 V logic 1 else 0
pin[4] - return logic state of AN1 pin (0/1) - If voltage > 2.5 V logic 1 else 0
pin[5] - return logic state of AN2 pin (0/1) - If voltage > 2.5 V logic 1 else 0

HWZA can be powered from 9 to 20 V DC.

All software is OPEN SOURCE ( bootloader program and firmware ) written in MikroPascal and MikroBasic language.

How do you purchase?

I would like to buy one or two, but I can't see how to make such an order. Perhaps a link in the post or some instructions on how to order would be nice, or instructions about when I can buy. :-)

Yes, SORRY , you can buy this product from here :

Is it possible to power these modules via poe (power over ethernet)?

[yo2lio]

Directly No !

But you can transport DC power over Ethernet , cut white_blue/blue and white_brown/brown wire from RJ45 male connector and connect this on my POWER DC IN green connector.

Regards Florin.

That could be a solution, but in your specifications you write that your module supports a DC-range 12-24V. PoE transports a range between 44V to 54V DC. Or does your module support this range too?
